5 E s s E N n w springs both in pulling and in draft. The parts are simple and not liable to get out of order and the device may be cheaply made and assembled.

Various changes may be made in the details of construct-ion and arrangement of the parts Without departing from the spirit and scope of my invention as defined in the appended claims.

I claim:

1. In a draft rigging, a plunger member adapted to be connected to a car frame, a draft member having coupling means at its forward end and provided with a casing portion at its rear end portion which telescopes over the plunger member, a plurality of keys connecting said members, the members being slotted to permit endwise movement of the draft member, and a plurality of springs arranged in tandem and within said casing portion and provided with bearings whereby they sustain both buffing and pulling stresses, one bearing of each spring be ing carried by the plunger and the other bearing of each spring being carried by the draft member substantially as described.

2. In a draft rigging, a-plunger member adapted to be pivotally connected to a car frame a draft member ha'vin a casin 0r-. 7 D 0 tion telescoping over the plunger member and arranged to swing therewith, three keys extending through the casing portion of the draft member and the plunger member, the casing portion and plunger member having elongated slots to receivethe front and rear keys, and the casing portion only having an elongated slot to receive the intermediate ltey, two springs seated within the casing portion between the keys, the forward spring having a rigid bearing on the plunger member at its forward end and the rear spring having a rigid bearing on the plunger member at its rear end, and bearings for the inner ends of the springs seated against the intermediate key, substantially as described.

3. In adraft rigging, a plunger member adapted to be connected to a car frame, a draft member provided with coupling means and having a casing portion fitting telescopically over the plunger member, a forward key extending through the draft and plunger members and normally fixed against forward movement, but capable of rearward movement, a rear keyalso extending through the draft and plunger members and nor-' mally held against rearward movement but capable of forward movement, an intermediate key member connecting the plunger and draft members and held against-both forward and rearward movement, springs arranged in tandem within the casing por- ERNEST H.
